SUBMEBSION CONTROL FOR DIVERS AEIVIGR WITH FLEXED MEMBERS.

reasons.

Application filed May 20, 1914.

To (ZZZ whom it may concern Be it known that 1, Gross SronLn, a citizenof the German Empire, residing at Kiel, in the Kingdom of Prussia,Germany,- lVerk Revensberg am Habsburger Ring, have invented certain newand useful Improvements in Submersion Controls for Divers Armor withFlexed Members, of which the following is a specification.

In divers suits of flexible materials the ascensional power of the divermay easily be varied by varying the gas charge inside the suit. but thismeans for producing a variable ascensional power which is so valuablefor the diver encounters considerable (litliculties when applied tonon-elastic metal clothes so-called divers armor. In such case the divercan indeed retard the ascent by the attachment of weights and accelerateit by releasing the weights, but a regulation of the depth of immersionand a further descent after the weights have been thrown ofl? is notpossible. The diver then must necessarily again be raised to the waterlevel.

The present invention therefore relates to an arrangement applicable toarmored diving suits by which the ascent can be regulated at will. Forthis purpose a vessel is provided on the diving device the gas contentsof which can be altered at will by the diver so that the volume of thevessel increases or diminishes corresponding to the charge. if thevessel is itself rigid the gas leaving the vessel may be displaced byliquid to increase the descent or vice versa. In the first case thevessel is for instance made out of parts telescoping one within theother or is in the form of an air bellows. The change of volume atconstant weight operates the change in the descent, while in the lattercase in which the container is rigidly connected with the diving devicethe variable liquid weight in this container produces the alteration inthe ascent condi tions. The operation of the valves necessar for thefunctioning of the device may usually take place from the inside of thediving device, which will for this purpose be made in. the usual mannerso that the diver can draw his arms into the interior of the divingdevice and move freely therein.

The invention is more particularly described with reference to thedrawing illustrating various forms of construction by way of example.

Figure 1 is a sectional elevation of a diving device according to myinvention. Fig. 2 illustrates, diagrammatically. the controlarrangement.

Referring to the drawings, a container 7) is shown as directly connectedwith a diving device and extends from the rear side of the devicedownward between the jointed members along the front side of the deviceeX tending upward. At this latter point, preferably on both sides, acompressed gas bottle (Z is arranged each of which is connected with thecontainer 1) by means of a pipe 0. The container 7) along its completeheight has a tube 9 passed through it. which allows liquid to pass intoand out of the container. Further, valves 6 are arranged on thecontainer controlling the gas inlet and the valve 7 controlling the gasoutlet, both of which can be controlled from the inside of the divingdevice.

The operation of this device is as follows hen the diver is sinking thecontainer 7) will be filled with water so that the greatest descendingpower is obtained. If the diver desires after he has reached apredetermined depth again to rise he will allow compressed gas to flowinto the container 5 through the valve 6. whereupon the water thereinwill be displaced and compressed gas will. take its place so that thedescent will be changed into an ascent and consequently the diver willrise. If when the rising movement is completed a sinking is desired thenthe gas out-let f is opened and consequently again water will enter.

By consequent control of both valves it is possible for the diver toadjust himself to any desired depth by controlling the contents of thecontainer Z) correspondingly to the wished for depth of submersion.

I declare that what I claim is 1. A diving device comprising a rigiddiving dress; a rigid buoyant chamber at tached thereto and separatedfrom communication with the interior thereof; a compressed air tankseparate from the interior of the diving dress; a discharge pipeconnecting the lower part of the interior of the chamber with theexterior; an exhaust pipe in the upper part of the chamber; a connectingpipe connecting the interior of the tank with the interior of thechamber; and valves in the connecting pipe and the exhaust pipe.

A diving device comprising a rigid diving; dress; a ri id buoyantchamber attached thereto and separated from communication with theinterior thereof, said chamber comprising one compartment; a compressedair tank separate from the in terior of the diving dress; a dischargepipe connecting the lower part of the interior of the chamber with theexterior; an exhaust pipe in the upper part of the buoyant chamher; aconnecting pipe connecting; the interior or" the tank with the interiorof the chamber; and valres in the connecting pipe and the exhaust pipe.

3. A diving device comprising a rigid diving dress; a rigid buoyantchamber at tached thereto and separated from communication with theinterior thereor and passing between the legs thereof; a compressed airtank separate from the interior of the diving dress; a discharge pipeconnecting the lower part of the interior of the cham her with theexterior; an exhaust pipe in the upper part of the chamber; a connectingpipe connecting the interior of the tank with the interior of thechamber; and valves in said connecting pipe and said exhaust pipe andoperable from the interior of said dress.

In testimony whereof I ilifiX my signature, in presence of twowitnesses.
